Follow-up questions

When and how did the United States get a standard currency, and what has been the process for making changes since then?

Are bills from most countries about the same size? Can you find any interesting stories behind the design of the bills from the country of your choice?

Since Cricket is a really popular sport in India, if you stacked a hundred dollars in 500 Rupee bills end-to-end the long way, would they be taller or shorter than a Cricket wicket? How about the Brazilian Real bill with a Hawksbill Turtle on it. Would bills worth $1000 US be taller or shorter than a soccer goalpost if stacked end-to-end the short way?
